Proposed Maintenance Weekend Dates for FY2014

CIS is seeking input on their proposed 4 quarterly maintenance weekends for the coming FY. If the dates below post an issue you know of, let me know. There will be reminders sent as each date approaches should situations change in the intervening time.

Thanks!

As you’re probably aware, CIS schedules four maintenance weekends every year. These are weekends in which we do extensive maintenance to IT systems and services and, therefore, can’t guarantee that IT services will be running. With that said, we do make every effort to communicate what we believe will be impacted based upon the planned work. We are proposing the following dates for these maintenance weekends in FY14.

  • November 8-10, 2013
  • January 17-19, 2014 ♦
  • May 16-18, 2014 ♦
  • August 15-17, 2014

♦ Scheduled APS maintenance period

All clear, finally

Hello all,

After a [much!] longer than anticipated downtime the Apple File Server named silver.mcs.anl.gov is back on the network and available.

Thank you all for your patience with this and I’m very sorry for the inconvenience, we migrated up 2 major OS releases and to new higher capacity hardware. It should feel pretty snappy.

Please let us know immediately if you experience any unexpected issues

Thanks!

All clear, mostly

The planned maintenance is (mostly) done, with all externally exposed servers now back.

Things went well. Only the upgrade to our Mac file server (silver) is taking longer than planned and likely won’t be done until tomorrow.

Thus endeth the maintenance haiku festival on twitter.com/mcssys.

Thanks for your patience, all.

From 8AM until 8PM on Saturday, September 28th, we will be performing necessary maintenance on a number of servers to improve reliability and stability. The following servers and services will experience an outage in this window, some of them will be down for the entire window. We hope to not need the full 12 hours for this, but better safe than sorry.

  • git.kbase.us
  • caveat.mcs.anl.gov (trac.mpich.org)

The full list of affected mailing list domains can be found on the blog posts linked above. We will be tweeting progress on the work as it happens at http://twitter.com/mcssys for those that want to keep a close eye on things.

Thanks for your understanding and patience.

Mail migration schedule

This announcement is being sent out to anyone with a mailbox on the ANL Zimbra server in MCS, CELS, or ALCF rather than the broader CELS Systems Announcements list. You can also find this on the MCS Systems Blog at http://www.mcs.anl.gov/systems/blog, and the Systems Twitter feed at http://twitter.com/mcssys.

CIS is expecting to be able to start migrating MCS/LCF/CELS Zimbra users to Exchange beginning in mid to late October. Our group is going to work out a preliminary schedule for this migration, with the general expectation being 100 mailbox accounts per week.

If you have a reason to delay your migration (travel, upcoming events, etc.) between now and the end of November and would like to be instead scheduled in December, please send a note to systems@mcs.anl.gov indicating as such. Otherwise, we will include you in the scheduled moves prior to Thanksgiving.

Once you’re scheduled, you’ll get contacted by the CIS migration team who will walk you through the process. The MCS Systems Group is going to be migrated first, currently scheduled for October 14. Other migrations are tentatively scheduled to start 10/21.

As part of the migration, CIS will provide documentation and instructions on how to access your new mailbox. MCS Systems will help where we can.

Thanks!

Update: CELS IT Maintenance Weekend, 9/28-9/29

Please see the previous announcement here: http://wp.me/p3jwfN-4O

The outage window will start at 8AM on Saturday, September 28th. We’re allowing for a 12 hour window, though we hope to be done in half that time.

git.mcs.anl.gov and git.kbase.us are added to the list of affected servers and services.

Once this work is complete, all of the affected services should be much more reliable, since we’re moving the various servers and services from older hardware or hardware that has developed issues to newer and more reliable machines.

We’ll send another update prior to the work starting, and will send an all-clear when it’s complete.

Thanks!

CELS IT Maintenance Weekend, September 28/29. Zimbra upgrade tomorrow (9/14).

Hey, folks.

First up, a reminder that Zimbra is being upgraded by CIS tomorrow (9/14), with an outage window of 9AM to 3PM. During that time, Zimbra will be inaccessible. Any mail sent during that window will be delivered after the downtime.

Next up, we’ve got some maintenance work on our servers that we can’t put off any longer. And, because it’s not the type of work we can do without incurring a downtime, we’re scheduling it for a weekend, specifically September 28 and 29, beginning the morning of the 28th (exact time to be scheduled).

Due to the nature of this work, the services we’re working on will be down and offline for some period, up to 12 hours. We’re doing as much of what we can do with live machines in advance, but a lot of the work requires the machines to be down so the data can be moved to its new home. We’re still working out the likely outage windows, but what follows is the preliminary list of affected servers and services. If this presents an undue hardship to you, let me know as soon as possible so we can look at options.

Affected servers (services)
=====================

  • silver.mcs.anl.gov (Mac server, administrative file shares)
  • variant.mcs.anl.gov (Subversion/Trac for MCS, ALCF, KBase, MPICH)
  • git.mcs.anl.gov
  • git.kbase.us
  • caveat.mcs.anl.gov (trac.mpich.org)
  • coredb-2.mcs.anl.gov (backup mysql server)
  • blizzard.mcs.anl.gov (collab.mcs.anl.gov aka Confluence)
  • licman3.mcs.anl.gov (License server)
  • dust.mcs.anl.gov (ALCF Drupal staging server)
  • squall.mcs.anl.gov (ALCF Drupal production server — http://www.alcf.anl.gov)
  • owney.mcs.anl.gov (All mailman lists, see below)
  • rt.mcs.anl.gov (ticketing system) *5 minute window for reboot only

During the mailman server outage, no mail will be lost or bounced, simply delayed during the downtime. Mailing list domains that will be offline:

  • lists.alcf.anl.gov
  • lists.anl-external.org
  • lists.bgconsortium.org
  • lists.cels.anl.gov
  • lists.cogkit.org
  • lists.computingschool.anl.gov
  • lists.cosmea.mcs.anl.gov
  • lists.earthmicrobiome.org
  • lists.extremecomputingtraining.anl.gov
  • lists.for.testing.only
  • lists.globusonline.org
  • lists.globus.org
  • lists.i2u2.org
  • lists.icis.anl.gov
  • lists.ieeetcsc.org
  • lists.igsb.anl.gov
  • lists.kbase.us
  • lists.kbt.mcs.anl.gov
  • lists.lcrc.anl.gov
  • lists.mcs.anl.gov
  • lists.metagenomics.anl.gov
  • lists.mpich.org
  • lists.mren.org
  • lists.naise.anl.gov
  • lists.nmpdr.org
  • lists.seq-lib.org
  • lists.terragenome.org
  • lists.theseed.org

We expect the outages to be contained to Saturday the 28th, with the 29th reserved in case things go unexpectedly poorly.

Again, if any of this presents an undue hardship, let me know ASAP so we can explore our options for minimizing it. Thanks!

New team members

Greetings, all.

Just dropping a note to let you know we have a couple of new faces working at the help desk starting this week. Martino Henderson and Kevin Walker both joined us starting on Monday, and will be taking on help desk and user support while John and Max will be working on more in-depth projects.

Martino’s a 12 year veteran of IT support and a certified Mac Genius, and worked with the Apple Store in that capacity before moving on to other user support roles in various organizations including Northwestern University.

Kevin’s had over 18 years doing all levels of IT support, working for such organizations as Cricket Communications, Advocate Healthcare, and the University of Chicago.

We’re happy to have them on board, and know once we get them up to speed on how things work around here they’ll be solving problems quickly and helpfully. Say “hi” and introduce yourself when you see them.

Thanks!
